| Customer Reviews: Average Rating:  Rating : - Averages under 50 cents per battery! I need two of these for my car key remotes. The initial voltage is 3.36 volts. No matter what brand, you should check the voltage of ALL batteries even if you don't plan to use them right now (The best way is using a digital multi-meter - just insert the black and red leads into the front and back of the packaging to get a reading, without removing the battery). The packaging that I received is different from one pictured, and the brand name is Tian Qiu. I cannot be certain that these are REAL lithium batteries, as I don't know how to check. Lithiums should last a lot longer than alkalines. + See Full Customer Review |  |
